When connecting to server this happens in log:

Failed to connect to server: there are 6 missing blocks and items
Missing list: [Forestry:waxCapsuleFuel, Forestry:refractoryFuel, Forestry:canFuel, Forestry:refractoryOil, Forestry:canOil, Forestry:waxCapsuleOil]

When i'm deleting neiaddons, everything is fine.

That's really weird. Please upload a full log from a failed attempt.

I'm closing this issue as part of a spring cleaning of my issue trackers from old stuff.

If you believe it's a bug that is still relevant in Minecraft 1.12 - Feel free to reopen it.
